Now the question is, is it a natural process or there are some people behind this drop?
Can we assume that there are forces who can 'manage' the market like yesterday?
It was just a circumstance of correction which was because of consistent increase of the price of bitcoin. So it was natural to happen and can be managed also. For a hodler who is able to foresee the drop, the best would have been to sell out outrightly or to convert the btc into USDT and with that you won't have the lose experience. USDT and other stable coins are best use for such kind of predicted drop.
